Abstract (en)

[origin: EP3214460A1] A signal processor (2) is configured so as to compensate for a peak shift of the distance between an SAR sensor (1) and a target, the peak shift occurring in the received signal subjected to range compression performed by an image reconstruction processing unit (14) due to a movement of the SAR sensor (1) during a time period until a reflected wave of a pulse signal is received by the SAR sensor (1) after the pulse signal is emitted from the SAR sensor (1). As a result, even when the SAR sensor (1) moves, an SAR image in which no azimuth ambiguity occurs can be reconstructed.
